Terms of Service for MatFlow

1. License Grant & Permitted Use

TKM Soft grants you a non-exclusive, non-transferable, revocable license to download, install, and execute MatFlow on compatible Android devices for your personal, commercial workshop, culinary, or manufacturing inventory management, subject to these Terms.

You agree not to:

• Decompile, reverse engineer, disassemble, or attempt to derive the source code of the application, except as permitted by applicable law.
• Bypass, disable, or tamper with application security checks, licensing verification mechanisms, or feature gate boundaries.
• Rent, lease, lend, sell, sublicense, or distribute the application executable without explicit prior written authorization from TKM Soft.

2. User Content & Intellectual Property Ownership

Your Trade Secrets Belong to You: TKM Soft asserts no ownership rights over the recipes, material compositions, costing figures, or inventory entries you input into MatFlow. Because the software operates local-first, your proprietary craft secrets remain entirely under your control.

All trademarks, graphics, UI design architecture, source code, logos, and audio assets belonging to MatFlow and TKM Soft are the exclusive intellectual property of Burkan Emre Tokman and are protected by international copyright and intellectual property treaties.

3. In-App Purchases & Financial Terms

MatFlow provides optional digital licenses via the Google Play Store:

• MatFlow Pro (matflow_pro): An optional one-time In-App Purchase that permanently unlocks unlimited raw materials, unlimited recipe hierarchies, advanced production batch history, automated critical stock alarms, and unrestricted CSV import/export.
• Billing Processing: All financial transactions and payment card data are processed directly through Google Play Billing. TKM Soft does not collect, receive, or store credit card details.
• Refund Policy: In-app purchases are fulfilled digitally upon purchase. Refunds are governed by the standard Google Play Refund Policy. If you experience technical defects preventing access to purchased features, contact us at burkanemretokman@gmail.com with your Google Play order number for assistance.

4. Voluntary Rewarded Advertisements

Users on the free tier may voluntarily watch Google AdMob rewarded video ads to earn bonus material allowances or export quotas. Advertisements are never forced during core workflows. Ad availability is dependent on Google AdMob network fulfillment and device connectivity.

5. Data Responsibility & Backup Sovereignty

Because MatFlow stores your data locally in an SQLite Room database, you are solely responsible for maintaining regular backups of your inventory and recipe archives. TKM Soft does not host your business database and cannot recover records lost due to device damage, factory reset, or uninstallation without an existing backup.

Users may utilize the built-in CSV export tool or connect their personal Google Drive account to create encrypted cloud snapshots to safeguard against hardware failure.

6. Disclaimer of Warranties & Production Liability

MATFLOW IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED.

While the mathematical engine and inventory deduction mechanisms are designed with rigorous floating-point precision, you acknowledge and agree that:

• MatFlow is an operational calculation aid and inventory organizer, not an automated safety control system.
• You remain entirely responsible for verifying all physical safety measures, food safety regulations, chemical handling ratios, allergen controls, and industrial compliance standards for products you manufacture or distribute.
• TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, TKM SOFT SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, SPOILED INVENTORY, PRODUCTION DOWNTIME, OR WORKSHOP DISRUPTIONS ARISING OUT OF THE USE OR INABILITY TO USE THE APPLICATION.

7. Termination

You may terminate this agreement at any time by permanently deleting the application and associated local data from your device. TKM Soft reserves the right to terminate your license immediately if you violate any critical terms of this agreement.

8. Governing Law & Dispute Resolution

These Terms of Service are governed by and construed in accordance with the laws of the Republic of Turkey, without regard to its conflict of law principles. Any legal disputes arising in connection with these Terms shall be subject to the exclusive jurisdiction of the competent courts of Istanbul, Turkey.

9. Modifications to Terms

TKM Soft reserves the right to update or modify these Terms as necessary to comply with applicable regulations or app enhancements. The latest revised version will always be posted at tkmsoft.com/matflow-terms.html.
